If it works, for $7 it was worth every cent. I bought mine new and I love it. Truly a great card for any PCI PowerMac (while Sonnet says G3 onwards, I've heard reports of it working in pre-G3 PCI PowerMacs)

For the record, they don't come with a CD. Well, mine didn't anyway. I put it in my G3 and it saw the card right away (recognised it as a SCSI card), and I was able to connect and use drives straight out of the box. And you should be able to format HDDs with any drive utility - Drive Setup works fine.
